The partial pressure of HYDROGEN in the mixture of 1.22 atmExplanation:We know that partial pressure of a gas is the product of the “TOTAL pressure” and the CONCENTRATION or the “mole FRACTION of a gas” in the mixture.Partial pressure = Total pressure × Mole fractionLet the moles of each gas be X.We know that the atomic MASSES given below:So, we have the mole fraction of each gas which is given below:The total moles of the gas mixture Now, to calculate the partial pressure of :Partial pressure = Total pressure × Mole fractionPartial pressure = 1.22 atmRead more on Brainly.in - brainly.in/question/1467772#readmoreExplanation:The partial pressure of hydrogen in the mixture of 1.22 atmExplanation:

(a) WATER at ROOM temperature is LIQUID because at this temperature (i)it has fixed volume and (II)it can flow. (B) An iron almirah is solid at room temperature because at this temperature (i) it has definite shape ALONG with fixed volume and (ii) It can not flow like water and hence does not possess fluidity

Therefore, the OXIDATION number of sulfur is +4 (it LOST FOUR electrons to OXYGEN) and the oxidation numbers for our compound is as follows: Na +1; S +4; O -2. You can also do this ALGEBRAICALLY by setting up an equation equal to zero.

e displacement reaction is a type of chemical reaction in which the reactant IONS EXCHANGE places to form NEW products. Usually, a double displacement reaction results in precipitate formation. The chemical bonds between the REACTANTS may be either COVALENT or ionic.hope you like the answer ☺️

The IMPORTANCE Of Benzenediazonium Salts In The Synthesis Of Organic COMPOUNDS Are As Follows : 1.They find application in the dye and PIGMENT industries and are used to produce dyed fabrics.2.Due to their property of breaking down near the ultraviolet light, they are used in document reproduction3.They are useful in the synthesis of a large variety of organic compounds, especially aryl derivatives.4.Direct halogenation is not a suitable method for preparing aryl iodides and fluorides. Nucleophilic substitution of chlorine in chlorobenzene by a cyano group is not possible. HOWEVER, diazonium salts can easily be used to produce cyanobenzene.5.It is not possible to prepare substituted aromatic compounds by direct substitution in benzene. For these compounds, we use the replacement of the diazo group in diazonium salts.6.They are used as INTERMEDIATES for introducing –F, –Br, –Cl, –I, –NO2, –OH and –CN groups into the aromatic ring.

tion:Aqueous SOLUTION of Sodium sulphate when mixed with Barium chloride ,we get a SALT named Sodium chloride with Barium sulphate. This chemical reaction is TERMED as Double-Displacement reaction , because…… AX +By ——— BX + Ay.

First electron affinity is endothermic for NEGATIVE SIGN......

Explanation:If we compare the structures of chloro-benzene and 1-chloro-4-nitrobenzene then in one structure there is presence of nitro group (-NO_2)(−NO 2​ ) which is very strong electron withdrawing activates the RING for the nucleophilic attackWhen the reaction with chloro-4-nitrobenzene OCCURS, SNAR mechanism takes PLACE, because Meisenheimer's INTERMEDIATE is stabilized by resonance

plz follow meExplanation:nice VIDEO has to go back and family are doing great weekend as you are INTERESTED and family so much R all of your help in any case we don't understand how you SIR I can do it I am student and sir I have some ANSWER

O2 means we have 0.25 moles of O2.  As, 1 MOLE has 6.023*10^23 molecules, 0.25 moles of O2 will have 0.25*6.023*10^23 molecules=1.50575*10^23 molecules and as 1 molecule of O2 has 2 atoms, so, 1.50575*10^23 molecules will have 2*1.50575*10^23 atoms=3.0115*10^23 atoms of O.Explanation:At NTP , one mole of a gas occupies a volume of 22.4 L . This particular volume is KNOWN as molar volume . Also we know that one mole of a gas contains avogadro number of molecules and it contains atoms EQUAL to the PRODUCT of number of molecules and atomicity . The atomicity of oxygen is 2 , so 1 mole of oxygen contains atoms equal to 2 times the number of molecules Therefore we can SAY that 22.4 L of Oxygen contains = 6.023 * 10^(23) molecules 1 L of Oxygen contains = 6.023 * 10^(23)/22.4 molecules 5.6 L of Oxygen contains = 6.023 * 10^(23) * 5.6/22.4 molecules 5.6 L of Oxygen contains = 6.023 * 10^(23)/4 molecules 5.6 L of Oxygen contains = 1.50575 * 10^(23) molecules Therefore , 5.6 L of Oxygen contains = 1.50575 * 10^(23) * 2 atoms 5.6 L of Oxygen contains = 3.0115 * 10^(23) atomsHope it helps....please mark as brainliest.

propan-1-olExplanation:

We look at FIVE states of matter on the SITE. Solids, liquids, gases, PLASMAS, and Bose-Einstein condensates (BEC) are different states of matter that have different physical properties. Solids are often HARD, liquids FILL containers, and gases surround us in the air. Each of these states is also known as a phase.hope it helps ❤

Allotropy or ALLOTROPISM (from ANCIENT Greek ἄλλος (allos), meaning 'other', and τρόπος (tropos), meaning 'manner, FORM') is the property of some chemical elements to EXIST in two or more different forms, in the same physical state, KNOWN as allotropes of the elements.hope it helps ❤

Aufbau Principle suggests that the electrons be FILLED into different orbitals in the increasing order of energy STARTING with the ORBITAL with the lowest energy. Relative energies of VARIOUS orbitals is given by (n+l) Rule. Here lesser the value for (n+l), lesser will be the energy. And the one with lesser energy gets filled first according to Aufbau Principle. For 4s - n = 4 , s = 0 , (n+l) = 4FOR 3d-n = 3 , d= 2 , (n+l) = 5 Hence 4s is filled first. Remember the values of 'l' for orbitals s = 0 p = 1d = 2 f = 3

Barium Nitrate - Ba(NO3)2Barium Sulphate - BaSO4NO3- ion has -1 CHARGE and Ba2+ has +2 charge. HENCE by cross MULTIPLICATION Ba(NO3)2SO42- has -2 charge hence cross multiplication RESULTS in cancelation of +2 of Ba and -2 of SO4. Hence BaSO4.

It is defined as the 1/12 the the mass of carbon ATOM. it is needed because without it we can not CALCULATE MOLECULAR mass and ALSO can't calculate pressure exerted on that gas. Also we can't calculate Empirical mass of the compound

Underneath the frozen upper layer, the water remains in its liquid form and do not get the freeze. Oxygen is TRAPPED beneath the layer of ICE. As a result, fish and other aquatic animals find it POSSIBLE to live COMFORTABLY in the frozen ponds.HOPE THIS HELPS YOU ✌️
